Edge: Too Many Requests, response code = 429

[nishelby]

Mod edit: only reply if yf.__version__ prints latest version. Ignore PIP Conda etc

---

As many have experienced the 429 error when using yf download. I have upgraded to the latest yfinance v 0.2.54 (Successfully installed yfinance-0.2.54) and I am still getting the too many requests. How do I resolve this? Thank you for your help,

I upgraded to 02.54, but in my usual venv I get error 429 - too many requests.
The strange thing is that the same code used in a brand new venv (same machine, same Mac-OS), it works perfectly.

The log in the old venv (download not working):

Being all the other things the same, it looks like the difference could stay in the fact that in the old venv I just updated yfinance to latest version, while in the brand new venv I installed the new version from scratch.
Is there any way to "clean up" things for yfinance in an old environment?
Thank you in advance for any help with this.

encountered the same issue, upgraded yfinance to the latest version and problem solved

I've upgraded to 0.2.54, but still having issue. I wonder if creating a virtual env would help

...

hmm. I will try to create a new venv and see if that works

Also getting 429s. I also try to access Yahoo Finance directly with urllib.request.urlopen, varying the User-Agent header, and can no longer access. My guess is that they have deployed new safeguards against scraping.

I was getting the same errors and found this on stackoverflow(for anyone encountering this error using VSCode):

Use shortcuts "ctrl+shift+P" and type "Python: Clear Workspace Interpreter Settings" AND "Python: Select Interpreter" to change the environment.

I upgraded to 0.2.54 and it worked, but I also changed the user-agent to 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)' is it more tolerant for old browsers?

Only reply if you have issue with latest version.

Try manually changing user-agent here (need to edit code):

yfinance/yfinance/data.py

Line 64 in 403607c

'User-Agent': random.choice(USER_AGENTS)

When problems occurred using the yfinance download methods reverted to scraping, using "https://query2.finance.yahoo.com/v8/finance/chart/Ticker". This worked until this week and then resulted in too Many Requests error. Did notice this at the end of the data retrieval, https://query2.finance.yahoo.com/v7/finance/chart/ACIW?interval=1d&range=5y, the request was complete with data and ended as 0.560001373291016]}]}}],"error":null}}. Not sure if this is the issue, and not sure how to get around it.
